Twitter Media Failed to Upload: How to Fix It

The “Some of your media failed to upload” message on Twitter, now called X, means one or more photos or videos did not attach successfully to your post. Work through the checks below to identify whether the issue is the file, your connection, the app or browser, or a temporary service problem; you may need the original media files and access to a stable internet connection.

What You’ll Need

• The photo or video you intended to post, preferably saved locally on your device.
• A reliable Wi-Fi or mobile-data connection, and access to the account you are posting from.
• The latest available version of the X app, or a current browser if you post on the web.

Step-by-Step

1. Check which item failed. If you attached several files, remove them and try uploading one at a time. If one file consistently fails while others work, focus on that file’s format, size, or condition. If none work, check the connection, app, and service status before changing your media.
2. Confirm the connection. Open a web page or another app that uses the internet. If loading is slow or fails, switch between Wi-Fi and mobile data, or move closer to the router. Temporarily turn off a VPN or proxy if you use one, then retry. Avoid repeatedly tapping Post while the connection is unstable; you could create duplicate posts if an earlier attempt actually went through.
3. Check whether X is having an outage. Look at X’s official status information, if available, and check whether other users are reporting upload problems. During a service disruption, wait and try again later. Reinstalling or editing a file is unlikely to help if uploads are failing for many people.
4. Review the media file. Make sure the file opens and plays or displays correctly on your device. If it is stored only in cloud storage, download it fully before attaching it. For a video, try exporting a fresh copy in a commonly supported format such as MP4, using standard video and audio encoding. For a photo, save or export a new copy as JPEG or PNG. Avoid unusual formats, damaged files, and files renamed without actually being converted.
5. Check the current upload requirements. X’s supported media types, maximum file sizes, video duration limits, and account-specific features can change. Check the current Help Center guidance for the type of media and account you are using. If the file is over a stated limit, shorten or compress it with a reputable editor, or reduce its dimensions or quality. Do not assume that a file accepted by another service will meet X’s requirements.
6. Try a fresh post with one attachment. Start a new post rather than continuing to reuse a draft that may have an incomplete upload. Attach one file, wait for its thumbnail or upload progress to finish, and then post. If it succeeds, add any other media one at a time. If a multi-file post fails, this helps isolate the item or combination causing the problem.
7. Refresh the app or browser. In the app, close it completely and reopen it. On the web, refresh the page, sign in again if prompted, and try a private or incognito window. A private window can help identify extensions or stored site data that interfere with uploading. If it works there, disable extensions one at a time or clear site data for X, then sign in again.
8. Update the app and restart the device. Install any available X app update from your device’s official app store. Restarting the device can clear a temporary app or network problem. Then open X, attach the local file again, and wait for the upload to finish before posting.
9. Check permissions and available space. On a phone, confirm that X can access the photos or files you are trying to attach. The exact permission labels vary by operating system; look in the device’s Settings app under X or app permissions. If the media is not visible, grant access to the relevant photo or file, or save it somewhere the app can reach. Also make sure the device has enough free storage to process the upload.
10. Clear temporary app data or reinstall as a last resort. On Android, the app’s settings may offer an option to clear cache; avoid choosing clear storage or data unless you understand that it can remove local app data and sign you out. On iPhone or iPad, there may not be a separate cache-clearing option, so updating, restarting, or reinstalling may be the practical alternatives. Before reinstalling, ensure you know how to sign back in and that any drafts you need are saved elsewhere.

Common Mistakes

• Retrying a post without checking whether it published. Open your profile or timeline first; a slow response can make a successful post look like a failure.
• Changing the file extension only. Renaming a file from one extension to another does not convert its format. Export it through an editor or converter instead.
• Editing several things at once. Test one file and one change at a time so you can tell what fixed the issue.
• Deleting app data too early. Clearing storage or reinstalling can remove local drafts or settings. Try simpler steps first.
• Ignoring account or post limits. A file can be valid but still fail because it exceeds a current limit or the account does not have access to that upload feature.

Tips

• Keep an unchanged copy of the original image or video before compressing or converting it.
• Use a descriptive filename and store the file locally until the post is confirmed.
• For large videos, use a stable connection and leave X open while the upload completes. Avoid switching networks midway.
• After posting, check the published post to confirm that every attachment appears and plays or opens correctly.

Troubleshooting

Only one photo or video fails: Open it outside X, download it from cloud storage if needed, and make a fresh export in a supported format. Check the current size and duration requirements. If the replacement also fails but other files upload, the file may be damaged or incompatible.

Every attachment fails: Test another network, restart X, and try a browser or device if available. Check for an outage and confirm that your account can use the relevant media feature. If uploads fail across networks and devices after the service is operating normally, contact X Support with the device type, app or browser, approximate time, and file type. Do not send a password or private sign-in code.

The upload appears stuck: Give it a little time on a stable connection, then check your profile before retrying. If no post appeared, cancel the attempt, reopen X, and try one smaller or freshly exported file. If the post appeared without all attachments, create a new post with the missing media rather than assuming the incomplete upload will repair itself.

The app cannot see your media: Review photo or file permissions in device settings. If you use limited photo access, add the specific item or choose a different accessible file. Confirm that the file has finished downloading and is not merely a cloud placeholder.

Frequently Asked Questions

What does “Some of your media failed to upload” mean?
It means X could not attach at least one selected photo or video. The cause may be a network interruption, an unsupported or damaged file, an upload limit, or a temporary app or service issue.

Will my post publish if only some media uploaded?
It may publish with only the attachments that uploaded, or the post may fail altogether. Check your profile or timeline before trying again so you do not accidentally duplicate it.

Does converting a video to MP4 always fix the error?
No. MP4 is commonly supported, but the video’s encoding, size, duration, or other requirements can still matter. Check X’s current guidance and export a compatible file.

Why does the upload work on Wi-Fi but not mobile data?
Mobile coverage, data restrictions, or network settings may interrupt a large upload. Try a stronger connection and check whether your device restricts X’s use of mobile data.

Can I fix this without deleting the app?
Usually. Test the file and connection, restart or update the app, check permissions, and try the web version first. Reinstall only if those steps do not help.

What if it still fails after I try everything?
Check for service problems and contact X Support if the issue continues. Include the file type, device, app or browser, and troubleshooting steps, but never share your password or verification codes.
